All laptop manufacturers are working on developing more powerful laptops equilibrium, and the design of the hardware become easier to use, but for an affordable laptop, people always ignore the Battery performance and use until the laptop battery has problems. In fact, the laptop battery with the need to be more careful about some good habits can help you save money to buy a new battery, after all the battery price is still expensive, occupy about 10% to 15% of a laptop, and it is consumer goods. The laptop battery type and material, there are four categories of laptop battery: 1.Ni-Cd, 2.Ni-MH 3.Li-ion 4.fuel (AFC, PAFC, MCFC, SOFC, PEMFC, etc. )
Let us look at these four categories:
1.Ni-Cd Battery old laptop using Ni-Cd, becauese technology, there are many disadvantages of NiCd batteries roomage take a lot of weight, low-capacity, short life, the memory effect .. ., it is not using the laptop battery now.
2.Ni-MH battery Ni-MH is the protection of the environment most of these four types. But the weight, capacity, memory effect, this is not as good as the Li-ion.
3.Li Li-ion batteries have many excellent other than batteries.high operating voltage, low, high load capacity up safe range and speed, temperature scale, the effect of low memory, no contaminated.But environment of the Li-ion batteries still have a deficiency, it is expensive and time limit load (over the Li-ion 400 to 600 times to load some have good 800times).
4.fuel is a battery chemistry, and so expensive, we do not see much of the fuel cell market, in order not to introduce it.
